Ran 15,000 miles on M1 HM 5W30 with a M1 filter. The oil dipped low at least once. Low as in not even present on the dipstick. Has had at least 1.5 to 2 quarts of makeup oil added. Ran entire time with leaky air filter box. Water is probably present from me not really heating up the car before sampling. I ran the car for maybe 30 seconds to get it into the garage.

In any case, after I pulled the drain plug and sampled the oil, I put the old oil back in. Looks like I made the right call, the oil still has some life left!
